Monthly Actual Cost vs Monthly Contract Amount - sql

Question

I have a project that pulls cost per category (labor, equipment, indirect), per month for a job and then shows a running, cumulative total of the contract amount per month. (This calculation is based on the total contract amount divided by the number of months in a project. Then the second month is the first month + second month, third month is first month + second month + third month, etc.)
I have the query shown below. When I run this, it returns the data shown under current results. What I need is the running total column populated even when there are no costs as shown under expected results. How do I accomplish this?
Current results:
fiscalMonth
Labor
Equipment
Indirect
RunningTotal
ContractPerMonth

Answer 1

I was actually able to figure out how to accomplish what I needed. I modified how I created my table (changed table name from #costs to #months). This pulled the months, row number, and contract amount. I then joined it to my existing cost query. In SSRS, I'm able to calculate the running total by multiplying the monthly contract amount by the row number. Seems to be working.
create table #months (JCCo numeric, Job varchar(10), StartDate date, EndDate date)
insert into #months
SELECT JCCo,Contract,StartMonth, ProjCloseDate FROM JCCM WHERE JCCo = (#Company) AND Contract = (#Job);
with Q1 as
(
select JCCo,Job,StartDate as Mth
from #months
union all
select q.JCCo,q.Job,DATEADD(m, 1, q.Mth)
from Q1 q
inner join #months t on t.Job = q.Job
where Mth <= (DATEADD(MONTH,-1,t.EndDate))
)
select ROW_NUMBER() OVER ( order by Q1.Job, Q1.Mth) as Row#, Q1.JCCo, Q1.Job, Q1.Mth as fiscalMonth, ISNULL(cd.LaborCost,0) as Labor, ISNULL(cd.EquipmentCost,0) as Equipment, ISNULL(cd.IndirectCost,0) as Indirect, CAST(cm.ContractAmt / ((DATEDIFF(Month,cm.StartMonth,cm.ProjCloseDate)+1)) as DECIMAL(12,2)) as MonthlyContract, cm.ContractAmt as TotalContract
from Q1
